I know the consensus is that Carol Danvers didn't come across as an interesting character in her movie and was lacking in personality. I always chalked that up to the script more than anything else and the character was kind of handcuffed with the whole amnesia thing. She's not in Endgame enough to expand on anything either so there's a bit of a problem moving forward.

My solution: have Moonstone (Dr. Karla Sofen) be the antagonist in The Marvels. If Carol is working for some sort of agency on Earth, S.H.I.E.L.D., S.W.O.R.D., or otherwise, have her take psychiatric sessions with Sofen as a condition of service. Sofen can work with her to explore memories and other aspects of who she is. Maybe Carol is trying to deal with the sudden celebrity status and she doesn't feel like she deserves it. She can talk about how she feels about losing Maria. This lets us get to know the character better and it makes a connection between the hero and villain in a very intimate way. The twist would be that Karla is using Carol for her own ends, learning about her experiences and knowledge about alien cultures. She would learn about the moonstone and take it for herself. She'd be able to use Carol's fears and doubts against her on top of being a physical threat. Throw in Michael Rossi as a love interest and you'd have a lot to work with to help make Carol a better character. Monica Rambeau and Kamala being involved would help, too, but I think my idea has some legs, no?
